ERBB2 (v-erb-b2 avian erythroblastic leukemia viral oncogene homolog 2, also known as HER2 and neu) is a gene that encodes for the receptor tyrosine-protein kinase erbB-2. ERBB2 has been found to be amplified with an increased copy number in several cancers (PMID: 20185938). Amplification of ERBB2 promotes tumorigenesis and pathogenesis of several human cancers (PMID: 17471238). Recently, in breast cancer patients without ERBB2 gene amplification, activating ERBB2 mutations have also been identified (PMID: 23220880).

ERBB2 is altered in 5.46% of all cancers with breast carcinoma, non-small cell lung carcinoma, colorectal adenocarcinoma, bladder carcinoma, and uterine corpus neoplasm having the greatest prevalence of alterations [3].

ERBB2 GENIE Cases - Top Diseases

The most common alterations in ERBB2 are ERBB2 Amplification (3.82%), ERBB2 Mutation (3.69%), ERBB2 S310F (0.32%), ERBB2 Y772_A775dup (0.28%), and ERBB2 L755S (0.23%) [3].
